This has been reported for some time but there hasn't seem to be any fixes, not sure why it isn't high priority cuz it's op as <snip> but...
This valkyrie full set effect - Penetrate Defense: 500 is broken. It allows the player to hit over 25k white damage which results in over 120k+ crit damage randomly. Low chance, like 5%? A twin is abusing that set effect in 85 bsq.
Look at that crit, 148k. That'll one-shot alot of people. Can this get a fix already.
Fyi, that's +20 gears.
